Abstract

L'invention porte sur un procédé et un appareil pour surveiller un bruit ambiant lorsqu'un utilisateur écoute des signaux audio par des écouteurs. Lorsqu'un signal d'entrée audio est reçu, le signal d'entrée audio est transmis à des haut-parleurs dans les écouteurs. Un signal d'entrée de bruit provenant de l'environnement autour des écouteurs est reçu et analysé pour détecter des sons prédéterminés. La transmission du signal d'entrée audio est arrêtée lorsque des caractéristiques de bruit prédéterminées sont détectées dans le signal d'entrée de bruit.
